Seth Adams was fatally shot by Sgt. Michael Custer outside A One Stop Garden Shop late Wednesday night. A family spokesman called the shooting senseless.

Speaking at a news conference Friday afternoon, Bradshaw first shared what he called an updated picture of Adams and then explained his version of what led to the shooting.

Bradshaw said Custer was in an unmarked car conducting surveillance when Adams pulled up and started cursing at Custer. The sheriff said Custer identified himself as a deputy and showed Adams his identification and badge, but Adams attacked Custer after both men got of their cars.

"Adams lunged at the deputy, grabbed him by the throat and began to choke him," Bradshaw explained. "Custer was able to break free of that, drew his firearm and told Mr. Adams, 'You're under arrest.'"

Bradshaw said Adams ignored the order and instead went to his car, reached inside and then approached Custer with his hands close together. Bradshaw said Custer thought he had a gun and shot him. Adams was flown to St. Mary's Medical Center, where he later died.

"This individual made some bad choices," Bradshaw said. "The first choice was to argue with the deputy. The second choice is to assault a law enforcement officer. If you're going to assault a law enforcement officer or a deputy sheriff, then you need to be prepared to suffer the consequences."

Bradshaw said Adams had no weapons on him or in his car, but the sheriff said Custer had no way of knowing that.

Gen. David Petraeus pleaded guilty to federal charges Tuesday to end a probe into whether he provided classified information to his mistress when he was CIA director, according to a U.S. official briefed on the matter.
